Lets's calculate LCM of 969,644
Given numbers has no common factors except 1. So, there LCM is their product i.e 624036
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/624036
Therefore, the GCF of Fractions 407/969,208/644 is 1/624036
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 969,644 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(969,644) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(969,644) x common factors =1 x 1 = 1
LCM(969,644) = ( 969 × 644 ) / 1
LCM(969,644) = 624036 / 1
LCM(969,644) = 624036
